Using and Applying Maths is a brand new strand for our best-selling series 'Developing Numeracy'. There is one book of photocopiable maths activity sheets for each year of primary school. These books make explicit the skills and processes that pupils need to develop, and provide a wide range of activities and investigations ideal for classroom use. As the dust settles from the introduction of the National Numeracy Strategy, teachers are becoming aware that maths lessons have recently become very content-led. They feel they must now focus more on the skills and processes that pupils need to solve problems and carry out mathematical investigations. Also, a change to the SATs last year saw an attempt to assess these skills through written tests.
